COMBINED "VINE srnri Application filed ilGiJOl'ltBl as To all whom itmay concern Be it known that l, llnwiinn U. Lorrnnss a citizen of theUnited :ates, residin gg at Gibbon, in the county of flibley and Stateof hflinnesota have invented certain new and useful improvements in(loinbined dine Strippers and Bean or llea rs of which the following isa specificatmn.

This invention relates to new and useful improvements in combined vino:.-;trippers and bean or pea hullers, and has for the primary objectthereof, the provision of such a machine that is comparatively simple ofconstruction, inexpensive of n1ainifacture, simple of operation andhighly useful of purpose.

A further object of the invention resides in the provision. of aplurality of movable stripper eleinents adapted to cooperate with aplurality of interchangeable stationary stripper elements for strippinthe pods from the vines and for reinovin jhe peas or beans therefrom,the said stationary stripper elements being so constructed as to bereadily renewable when occasion demands.

The nature and. advantages of the inven tion will be better understoodwhen the following detailed description is read. in connection with theaccompanying drawings the invention. residing in the constructioncombination, and arrangement of parts as claimed.

In the drawhngs forming part of this ap plication, like runners-ls ofrefer ncc indi cate similar parts in the several views, and whereinFigure Ii. an. elei' ational view of one side of the machine constructedin accord ance with the pr sent invention and llfigure 2- ;is a verticallongitudinal 1-roi'-:s sectional view of the device.

fidpecifically described, the invention contemplates the provision of amachine for stripping; beans and peas from their vines, and extractingthe same from the pods. The machine includes a 3lui.'ality of stationarystrippers adapted to cooperate with an end less movable apron, havingsimilar strippers associated therewith. the peas and beans on the vinesadapted to engage between the movable and stationary strippers wherebythe same are stripped from the vines and a so removed from the pods. Theinvention further contemplates the provision. of a shaker screenpositioned forwardly of the outlet end of the mach inc whereby the vines1.. lftitil (lift Philip ."t'iEULLIlJilTt liittfll. h'erial Ill'o.iiill'idiflii.

and pods are separated from the beans and peas, a blast fan beingprovided beneath the screen for blowing;- away the foreign mat-ten butallowing the beans and iieas to pass th(nethrough onto anotherseparation screen and thence into a eontainerf ll ith particularreference to the d 'awinpgai, the machine includes a relativelyelongated floor board l. having vertically entemlinp; side walls 2, therear ends of which are of increased width and closed by a backing 3 forconstitutino a hopper 4i. Depending side walls 5 are also provided forthe floor board 1, and the forward ends of these walls 5 projecti-zligliitly forwardly of ti e front end of the said floor board forproposes-i herein after described. Secured to the side walls El and 5 ofthe floor board. are a front and rear pair 0: supporting legs 6 and iiii-aspectimely an intermediate pair of supporting it being; furtherprovided between the (3 and i". Hingedly secured as at 9 to a pointsligl'itly inwardly of the outer ends, and upon the upper surface ofeach. of the side walls is a longitudinally extending; strip 10., and atsubstantially the forward and rear ends of these opposite stripincinbers, and rotatably supported therebctween. is front and rearrotary shaft noeinber fl and 194 respectively. Each of these shafts haskeyed or otherwise secured thereto, a pair of sprocket wheels 13,inwardly of the spaced ends thereof and between the length tudinallyextending side strips 1d The alined sprocket wheels of the shaft ll. and153, are adapted to receive thercbetween endless sprocket chains 14:

its shown in Figures 1 and ii the rear sprocket wheel carrying shaft itengages through longritrulinaliy ciatendinp; slots 19 in the sidesupporting strips; 10, and the pro jeeting ends of this snaft engagethrough the eyed ends of eye bolts 20. The annular shanks of thesebolts, are threaded as shown, and are adapted to extend through openingswithin. the i it angularly bent ends 521 of SHPPOllZi'DQ, brachetssecured in proper position with respect to the slots 19 of the sidesupporting strips 10. if nut t3 has screw threaded engagement with theshank of each of the bolts 520 for moving these bolts longitudinallyupon the supporting strips when the nuts are rotated, and for conseqliei'rtiy applying suii icient attention to the opposite sprocket chainsi i. The forward shaft ll, has a pulley wheel 3:511;

secured thereto for receiving a belt thereon, from a suitable source ofpower (not shown).

In view of the hinged connections 9 for the side supporting strips 10,it will be readily appreciated that these strips together with theirassociated parts may be swung upwardly and outwardly, for obviouspurposes. As a means for retaining these strips 10 in an operativeposition, the rear ends of the same are provided with small perforationstherein for receiving the in nor ends of retaining pins 25, slidablypositioned within openings in the upper end of the rear supporting; 7.

Intermediate the ends of the tloorboard 1, and the vertically extendingside walls 2, the same are cut away for providing a relatively enlargedopening 26 therein. Positioned witl-iin this opening and supported attheir opposite ends by the upper edges of the depending side walls 5 area plurality of cross bars 27, preferably six in number, and havingextended vertically therethrough spikes or nails 28 constituting thestationary stripper elements. The nails or spikes or the bars 27 areinclined .in opposite direc tions to the similar nails or spikes 18 onthe movable stripper bars 17 as clearly shown, and it is to be notedthat the nails or spikes upon the movable and stationary stripper barsare arranged in staggered relation with respect to each other.

It will be seen that each alternate stripper bar 27 is so positioned asto have its stripper elements extended downwardly in an inoperativeposition. Any desired number of the stripper bars 27 may be positionedso as to have their stripper elements cooperate with the stripperelements 18 on the movable stripper bars 17, according to the proportionofthese stationary stripper bars being employed if the vines or the podsare in a wet or damp condition. As shown in Figure 1, longitudinallyextending strap irons 29 may be employed for retaining the sta tionarystripper bars in position, these strap irons being detachably secured'attheir opposite ends to the floor board 1. In view of this construction,it will be readily unden stood that the stationary stripper bars 27 maybe changed as occasion demands, and if any one of these stripper barsbecomes broken, the same may be readily renewed.

By referring to Figure 2, it will be seen that the forward end of thebase board or floor 1 is cut away for a portion of its lengthconstituting an opening 30 therein. Pivotally supported between thedepending side walls and front supporting legs 6 and hanging directlybeneath the opening 30 in the base board is a shaker screen, carryingperforated trays 36 denoted in general by the numeral 31. This shakerscreen is supported between the walls 5 and legs 6 by a front and rearpair of loosely mounted links 1.32am] 3;) respectively. The forward pairof links 82 are longer than the rear links, consequently supporting theshaker screen in a downwardly inclined position.

Secured to each side wall 3:) of the shaker, is a vertically extendingapron or shield 39, the upper edges of which lie within the adjacentdepending side walls 5 for guid ing the material to the shaker 3.1.

As a means for reciprocating this shaker, the lower connected ends ofthe front pai of link members 32 are pivotally engaged with rearwardlyextending connecting l,'ll .l-' l0, and the inner ends of thes rods arloosely disposed upon the crank portiou- 4.1 of a crank shaft 42. Thiscrank shaft is rotatably supported in l'iearings 43, car r ed by theupper edges of side strengthening bars 4-1, positioned between the frontand intermediate pair of supporting legs (3 and 8 respectively. One ofthe ends of the crank shaft 42 has a pulley 415 keyed thereto forreceiving therearound an endless belt 46, this belt also passing over apulley 47 keyed to the adjacent side of the shaft 11, whereby power isimparted to the crank shaft 42.

Between the intermediate pair of supporting legs 8 there is secured afan casing 48 having a fan wheel 49 therein, this fan wheel being keyedto a shaft 50 rd tatably supported at its opposite ends with-- inbearings 51 secured upon the vertical edges of the intermediatesupporting legs 8, a pulley wheel 52 being keyed to one and of the shaft50 and operatively connected to a pulley 53 upon the adjacent end of theshaft 11 by an endless belt An outlet end 55 of the casing 48 ispositioned beneath the upper end of the shaker screen 31 so as to directa blast of air through this screen for blowing away the vines, pods, andother chad.

Beneath the lower outlet end of the shaker screen 31 there is supportedbetween the forward pair of supporting legs 6 a stationary screen 56,inclined in an oposite direction to the inclination of the maker screen31. The outlet end of this screen 56 is disposed above a receptacle 57,sup ported upon side reinforcing bars 58 secured to the lower ends ofthe hereinbefore described supporting legs. In view of the abovedescription, it will be readily understood that the vines, with the peaand bean pods thereon are placed within the hopper 1-. These vines arefed beneath the stationary and movable strippers for re moving the podstherefrom and at the same time breaking these pods so as to allow thebeans or peas to disengage therefrom. A fter passing through thestrippers. the. material will be fed forwardly into the shaker screen31, whereby in view of the. shaking action of the screen and the airblast from ion the :lan 49, the vines and pode will be ef- :Eectivclyseparated from the beans and peas, and blown outwardly off the shakerscreen. The beans or peas will roll downwardly upon the upper tray andstrike the hoods thereon will pass through the open-- ings 37 therein,and thence upon the nexttray and similarly onto and through the bottomwall 34; of the shaker screen onto the stationary screen. 56 to beconveyed. thereby into the receptacle 57.

While the form of the invention herein shown and described is "what isbelieved to be the preferred ernbodin'ient thereof, it is nevertheleeeto be "iu'ideretood that various 'llorins, modilicat-ione andarrnnggeniente oi? the parts may be made without departing from thespirit and scope oil: the invention as claimed.

What- I claim as new is:

A vine stripper comprising a frame, a

lloor mounted horizontally thereon and ineluding removable cross barshaving; teeth thereon, a belt mounted for movement above the floor andhaving a lower run, which. is disposed parallel with the floor,transversely disposed bars carried by the belt, teeth carried by saidbars, means forllnoving the belt whereby the teeth which are carriedupon. the bars thereof may move between the teeth. which are supportedupon the floor, the teeth upon the floor being upwardly inclined in thedirection 031? the movement of the lower run of the belt, and the teethwhich are carried by the bare upon "the belt being; downwardly inclinedin a direct-ion opposite to the direction in which the lower run. of thebelt moves.
